ALEXANDER H. WHITTIGK, OF OLARKSVILLE, INDIANA.

IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 118,890, datedSeptember 12, 1871.

To all whom it may concern:

Be it known that I, ALEXANDER H. WHIT- TICK, of Olarksville, in thecounty of Clark and State of Indiana, have invented a new and usefulImprovement in Subsoil-Plows, and I do hereby declare the following is afull, clear, and exact description of the same, reference being had tothe annexed drawing making part of this spec ification, in which--Figure 1 is a perspective View of a plow with my subsoil attachment.Fig. 2 is a section on the line 00 a of Fig. 1.

The same letters are employed in both figures in the designation ofidentical parts.

My invention relates to a subsoiling attachment which may be connectedwith any of the breakingflows in common use, and which may be adjustedso as to cut ata greater or lesser depth, as desired.

In the annexed drawing, A is the beam, B B the handles, and G theland-side of an ordinary breaking-plow. D is the subsoiling attachment.It is bent in the form shown in the drawing, the top part being nearlyvertical and the point dhorizontal. The point is widened, as shown, to

throw up the subsoil, and the stem made sharp upon the edge at d, to cutroots and pass through the hard earth with a minimum of resistance. Atthe top of the stem or stock are a series of holes, I), through which abolt may be passed to attach it adjustably to the rear end of the beam,or to the handle B, or to both. Another series of boltholes are formedthrough the stem at D by means of which a brace, E, connecting it withthe beam A, may be in like manner adjustably attached to regulate theoperation of the cuttingpoint cl.

It is evident that the plow may be used with or without the subsoilingattachment; or, in other words, by the use of my improvement commonplows may be converted into subsoil-plows at a very small cost, thussaving to farmers the greater part of the cost of a heavy and expensiveplow not adapted to the ordinary work required on the farm.

I am aware that subsoil-cutters have been attached to other plows, and Ido not, therefore, claim broadly this combination; but

What I claim as my invention, and desire to secure by Letters Patent, is

1. The subsoil attachmentD, a section of which at x 00 presents the formsubstantially as shown in Fig. 2.

2. The combination of the subsoil attachment D, a section of which at m.90 presents the form substantially as shown in- Fig. 2, with the beam Aof an ordinary plow, and the adjustable brace E, arranged in relation toone another as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
